ios – 将数据传递到Swift中的Popover

概述在我目前的项目中,我有详细的视图,从我的表格视图显示一个特定的记录.我有以下标签 @IBOutlet weak var vacationImageView: UIImageView!@IBOutlet weak var percentSaved: UILabel!@IBOutlet weak var cost: UILabel!@IBOutlet weak var saved: UILab 在我目前的项目中,我有详细的视图,从我的表格视图显示一个特定的记录.我有以下标签

@IBOutlet weak var vacationImageVIEw: UIImageVIEw!@IBOutlet weak var percentSaved: UILabel!@IBOutlet weak var cost: UILabel!@IBOutlet weak var saved: UILabel!@IBOutlet weak var circleProgressVIEw: CircularProgressVIEw!@IBOutlet weak var daysDepart: UILabel!

我打电话给popover,我想将保存的当前文本值发送到我的d出窗口,允许用户编辑它并将其发送回视图.这是我的popover电话.

@IBAction func addPopover(sender: UIVIEw) {    let savingsinformationVIEwController = storyboard?.instantiateVIEwControllerWithIDentifIEr("SavingsAddPopover") as UIVIEwController    savingsinformationVIEwController.modalPresentationStyle = .Popover    savingsinformationVIEwController.preferredContentSize = CGSizeMake(200,200)    let popoverController = savingsinformationVIEwController.popoverPresentationController    popoverController?.sourceVIEw = sender    popoverController?.permittedArrowDirections = .Any    popoverController?.delegate = self    presentVIEwController(savingsinformationVIEwController,animated: true,completion: nil)}

我会以为我可以引用popover中的数据对象,但是至少不是我的想法.

解决方法

class VIEwController: UIVIEwController,SavingVIEwControllerDelegate,UIPopoverPresentationControllerDelegate{        @IBOutlet var labelText: UILabel!        overrIDe func vIEwDIDLoad() {            super.vIEwDIDLoad()            // Do any additional setup after loading the vIEw,typically from a nib.        }        @IBAction func buttonPopOverClick(sender: UIbutton)        {            let savingsinformationVIEwController = storyboard?.instantiateVIEwControllerWithIDentifIEr("SavingsAddPopoverVC") as SavingVIEwController            savingsinformationVIEwController.delegate = self            savingsinformationVIEwController.strSaveText=labelText.text            savingsinformationVIEwController.modalPresentationStyle = .Popover            if let popoverController = savingsinformationVIEwController.popoverPresentationController {                popoverController.sourceVIEw = sender                popoverController.sourceRect = sender.bounds                popoverController.permittedArrowDirections = .Any                popoverController.delegate = self            }            presentVIEwController(savingsinformationVIEwController,completion: nil)        }        func saveText(strText: Nsstring) {            labelText.text=strText        }        // MARK: - UIPopoverPresentationControllerDelegate        func adaptivePresentationStyleForPresentationController(controller: UIPresentationController!) -> UIModalPresentationStyle {            return .FullScreen        }        func presentationController(controller: UIPresentationController!,vIEwControllerForAdaptivePresentationStyle style: UIModalPresentationStyle) -> UIVIEwController! {            return UINavigationController(rootVIEwController: controller.presentedVIEwController)        }    }    protocol SavingVIEwControllerDelegate    {        func saveText(var strText : Nsstring)    }    class SavingVIEwController: UIVIEwController {        @IBOutlet var textFIEld: UITextFIEld!        var delegate : SavingVIEwControllerDelegate?        var strSaveText : Nsstring!        overrIDe func vIEwDIDLoad() {            super.vIEwDIDLoad()            textFIEld.text = strSaveText            // Do any additional setup after loading the vIEw.        }        @IBAction func buttonDone(sender: UIbutton)        {            if (self.delegate) != nil            {                delegate?.saveText(textFIEld.text)                self.dismissVIEwControllerAnimated(true,nil)            }        }    }
